1. Be connected between system bus and the storer, have a Memory Controller that is used between storer and system bus transmitting the memory of data steering logic and first data buffer at least, in case provide a kind of recoverable mistake that detects the data of reading from particular memory location just automatically to wipe the method for the ECC mistake the storer, this method may further comprise the steps:

  • The sense data that correction makes mistakes;

    The sense data that is corrected is stored in first data buffer;

    The sense data that is corrected that is stored in first data buffer is write on the write-back passage, and the input end of this write-back passage is connected between first data buffer and the system bus, and output terminal is connected with storer;

    AndTo be corrected sense data according to the storer control signal that produces by store control logic and be written to this particular storage from the write-back passage.
